vintage green paint cast metal toy fence, antique wrought iron style Christmas tree putz or dollhouse fencing

Four pieces of vintage cast metal decorative fence with worn original paint, made for a Christmas display or as a toy? I can't find any markings on these pieces, and am not certain of it's exact vintage.

I love the worn green paint and the very Victorian style. This would look so good with a dollhouse, or set up as a box around a small Christmas tree. There's some damage and wear to the hinges and latches, but it easily makes a complete square about 15" x 15", open at one corner.
